UebiMiau Leave messages on server

Currently, when UebiMiau checks mail, it removes the messages from the pop3 new messages, and they are not pulled by an external pop3 client later. I would like to know if there is a feature in UebiMiau that allows a message to remain as unread after checking, so that another client application will pull the messages on subsequent visits. I use this feature on my mail client application, so that if I dont have that computer, and check it from webmail, old messages will still be pulled. I have it configured to delete from server when deleted from trash on the client. I would really like to do the same thing in UebiMiau.
